Why I Love This Baked Blackened Salmon Recipe
Hello, I've been making blackened salmon the traditional skillet way with Cajun seasoning for years, and it's always been good. But lately, I've wanted something more hands-free in the evenings, especially during summers, so I've started baking it instead.
Once I figured out the little trick to keep it soft inside and crusty outside, while still loaded with smoky Cajun flavors, I never looked back to the skillet method.
Just like other salmon recipes, this baked blackened salmon is easy to prep. Simply toss the spices, then bake. You can even add veggies alongside to make it a complete dinner, or enjoy it just as it is.
Ingredients & Substitutions
- I used skin-on salmon fillets. I got them from the Costco frozen section. They come individually sealed, so I just drop them in a bowl of cold water for about half an hour to thaw. Once thawed, I remove them, rinse them, and pat them dry before sprinkling on all the seasoning. Feel free to use fresh or skinless salmon fillets, too.
- Olive oil, I brush it over the fillets until they are evenly coated. You can substitute olive oil with avocado or grape seed oil (these are my first choices), or use any neutral-flavored cooking oil.
- For the spices, I used a combination of paprika, garlic powder, onion powder, thyme, oregano, cayenne pepper, salt, and black pepper(see FAQ section for substitution options).
How To Make Baked Blackened Salmon
- Step 1. Preheat oven to 425°F and line a baking sheet with parchment paper. Thaw salmon to room temperature if frozen.
- Step 2. Mix paprika, garlic powder, onion powder, thyme, oregano, cayenne, salt, and black pepper in a small bowl.

- Step 3. Pat salmon dry, brush with olive oil, rub seasoning evenly over fillets, then lightly spray with cooking spray.
- Step 4. Bake for about 12 minutes until the salmon flakes easily. Adjust time for thickness. Serve hot with rice, pasta, or vegetables.
♨️How To Adjust The Heat Level
This baked blackened salmon has a medium level of heat, mostly from the paprika, cayenne pepper, and ground black pepper. It's flavorful with a nice kick, but not overly spicy.
- If you want to make it milder, just use half the cayenne pepper or skip it completely. You can swap it with smoked paprika for a richer, deeper flavor without the heat.
- If you like it extra spicy, increase the cayenne pepper and add some crushed red pepper flakes for more heat and depth.
The Leftovers & Meal Prep
You can use the leftover oven-baked blackened salmon to make salads, tacos, or a lunch bowl.
- Make this recipe in bulk and divide the cooked salmon into meal-prep containers.
- Store the leftovers in the refrigerator for up to 2 days, or in the freezer for longer storage. This freezer-friendly recipe can be stored for up to 2 months.
- To reheat, warm gently in the oven at 300°F or microwave in short intervals to avoid drying out.
The Secrets for Perfectly Moist Baked Blackened Salmon
Cooking oil and temperature are key to achieving soft, moist baked blackened salmon.
- Baking at 425°F seals the surface and keeps the inside tender and juicy as it cooks.
- Brushing the fillets with olive oil before seasoning also helps retain moisture.
- Spraying the fillets with oil after seasoning prevents the spices from drawing out moisture during baking.
Frequently Asked Questions
However, you can easily substitute all of these with a good store-bought Cajun seasoning or make your own at home. It's worth making a batch because you can use it for other Cajun recipes (like Cajun chicken stew or Cajun shrimp salad), too.
No need for flipping, just bake the salmon undisturbed. Place skin-side down if using skin-on fillets, or place directly on the baking sheet if using skinless.
Yes. Add quick-cooking veggies like asparagus, zucchini, or bell peppers to the same tray.
📖 Recipe
Baked Blackened Salmon
Ingredients
- 2 salmon fillets (about 6 oz each)
- 1 teaspoons olive oil
- 1½ teaspoons paprika
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon dried thyme
- ½ teaspoon dried oregano
- ¼ teaspoon cayenne pepper (adjust to taste)
- ¼ teaspoon salt
- ¼ teaspoon black pepper
- pam
Instructions
- Preheat your oven to 425°F. Line a baking sheet with parchment paper or aluminum foil for easy cleanup. If the salmon is frozen, thaw it to room temperature.
- In a small bowl, mix together the paprika, garlic powder, onion powder, thyme, oregano, cayenne pepper, salt, and black pepper.
- Pat the salmon dry with paper towels. Brush each fillet lightly with olive oil.
- Rub the seasoning mixture evenly over the top of each fillet. Lightly spray the fillets with cooking spray. This helps the spices stay in place and keeps the salmon from drying out.
- Place the salmon on the prepared baking sheet and bake for about 12 minutes, or until it flakes easily with a fork. For 1-inch thick fillets, 12 minutes works well. Thicker pieces may need a few extra minutes, while thinner ones will cook faster, check early to avoid overcooking.
- Serve hot with rice, pasta, or your favorite vegetables.
Notes
- Adjust heat easily: reduce or skip cayenne for mild flavor, or increase it and add red pepper flakes for extra spice; smoked paprika adds depth without heat.
- Store leftovers in the refrigerator up to 2 days or freeze up to 2 months; great for salads, tacos, or meal prep bowls.
- Reheat gently in a 300°F oven or microwave in short intervals to keep the salmon moist and prevent drying out.
